So, I’ve got this really annoying issue with my 2016 Expedition. Every time I turn on the AC, the belt starts squealing like it’s begging for mercy. The strange part is that it only happens when the AC is on—when it’s off, no noise at all. I’ve already checked the belt tension, and everything seems fine, so now I’m wondering if it’s something more specific, like one of the pulleys.
Could it be the AC compressor pulley or maybe the tensioner going bad? I’ve heard that sometimes the AC clutch can cause the belt to slip if it’s worn out, but I don’t know if that’s what’s going on here. The belt itself looks pretty new, no cracks or wear, so I doubt it’s the belt itself.
Anyone else run into this problem? Should I just replace the belt anyway or focus more on the pulleys and the AC compressor? I’m trying to avoid taking it to a mechanic if it’s something I can fix at home, but I don’t want to make it worse either. Any advice on how to diagnose this further or fix it would be much appreciated!
